Fix OneDrive Large Video Download Stuck at 0 Percent
Question details
Users are unable to track the download progress of large shared MP4 videos from OneDrive, as the download indicator remains permanently stuck at zero percent.

- Product
- Microsoft OneDrive
- Device & OS
- not provided
- Scenario
- Attempting to download 4-10 GB shared MP4 video files from OneDrive via a web browser.
- Observed behavior
- The shared videos can be played online smoothly, but when users initiate a download, the progress bar stays at 0% across different computers and networks, even though the file may actually be transferring in the background.
Verify that the recipient has the appropriate permissions to download the shared file and ensure there is sufficient local storage space available on the computer to accommodate the 4-10 GB video.
Verify Local Background Download Progress
Web browsers often fail to display accurate download progress for exceptionally large files on OneDrive, meaning the file may already be downloading successfully in the background.
When downloading massive media files (like 4-10 GB videos), the OneDrive web interface might lose sync with the browser's progress tracking. Before assuming the download has failed, you should check if the file is actively being written to your local drive.
Click the download button on the shared OneDrive video page and leave the browser window open, even if the progress indicates 0%.
Navigate to your computer's default 'Downloads' folder using File Explorer (Windows) or Finder (Mac).
Look for a partially downloaded file corresponding to your video. It may have an extension like '.crdownload' (for Chrome) or '.part' (for Firefox).
Right-click the temporary file and check its properties. If the file size is continuously increasing, the download is actively progressing. Do not cancel the process in your browser.

Use an Alternative Web Browser or Private Window
Switching browsers or using an incognito window can bypass cached data, cookies, or extensions that might be interfering with OneDrive's progress tracking scripts.
Clear Browser Cache and Disable Extensions
Outdated cache files and restrictive security extensions can block the background processes required to download large files and track their progress.

Frequently Asked Questions
Why does my OneDrive download stay at 0% but still download?
When downloading exceptionally large files like 4-10 GB MP4 videos, web browsers often struggle to accurately calculate the incoming data chunks from cloud servers. This results in the visual progress bar freezing at 0% while the actual file data transfers successfully in the background.
Can I use the OneDrive desktop app to download large shared videos?
Yes. If the sender grants you edit access or you can add the shared folder to your own OneDrive, you can use the OneDrive desktop application to sync the large video file directly to your File Explorer or Finder, bypassing browser limitations entirely.
Does file format affect OneDrive download progress tracking?
The format itself (like MP4) does not break progress tracking, but media files are typically much larger than standard documents. It is the massive file size rather than the format that causes browsers to drop the progress tracking connection.
How can I prevent large downloads from failing on OneDrive?
To ensure large downloads complete successfully, use a stable, hardwired internet connection, disable aggressive sleep or hibernation modes on your computer, and temporarily turn off browser extensions that manage or intercept downloads.
